Trying to connect Samsung tv bluray and sound bar with DVR cable box. Tried reading the e-manuals and booklets but I'm just confused. Please help before I go crazy.
I have no idea what your asking... Your trying to connect a a bluray player and a Cable box to a tv with soundbar?
The BEST option is get an A/V receiver, don't know if that's in your budget though.
If your tv has an audio out (I'm assuming you're not hoping for audiophile quality) Just plug soundbar into there, plug Bluray via HDMI or whatever cable/cables you'd like to one of your tv's inputs. Connect the cable box using HDMI or again whatever cable you'd like to another input to your TV, use the tv remote to switch inputs.
Hope this answers your question!
UPDATE: Just look at my post below I drew a diagram that depicts this much better.
